Cross-reference / replacement · Winbond → GigaDevice
- Density:

Compatibility & sourcing notes
Both are JEDEC-standard 3.0V 128Mbit SPI/Quad-SPI NOR in SOIC-8/WSON-8 with identical 4KB-sector/64KB-block layout and matching QE bit (SR2 bit1), so they swap on the same footprint. The one firmware caveat: the JEDEC ID differs (Winbond EFh vs GigaDevice C8h), so any ID whitelist must add C8 40 18 and allow longer erase timeouts. Confirm voltage, density, and timing per datasheet.
The two share a footprint and interface and can usually be swapped directly; before mass production, still confirm voltage, density, and timing against both datasheets.
